The Home Machinist!

Thanks everyone for chiming in, Harold V, machining a new sleeve from bar stock is tops on my list of methods to repair this, definitely easier and it probably hold up better than re brazing the broken parts together. The original part is most likely made of one piece. That's to prevent the sleeve ...

My thoughts as well. I was overly impressed with the entire train.

A great deal depends on what type of things you buy. I'm not keen on anything that has a motor, as they have been marginal, at best, in my few experiences. However, I've made some incredible purchases from HF with items that closely emulate the quality of items that used to be made in the good 'ol U...

every thing looks good except for that black object toward the end of the train with the ge logo on it

I saw no black object. I did see a large transformer, equipped with a GE logo, but it was gray. What did I miss?
Note that I did see the custom railcar, which was black in color.

Surprisingly the half of the vari speed pulley that goes over the motor shaft seems to not have any out of the ordinary play, the other half of the pulley that's broken that's the wobbler. It may not sound like a great idea, but making one from bar stock just might be your best solution. That it's ...

My SIL has done this to tree stumps, but I have not because some of the stumps on my property are close to live trees. If the Potassium Nitrate "burns" the roots underground, what is the possibility of the next tree roots catching and the 'fire' damaging that tree also? Inquiring minds, etc. --earl...

Although my initial impression is that the hollowed out back and top parrellel ridge make a perfect natural handhold. Which would also become a perfect source of heat transfer from your hands to the straight edge. Handles are intended to limit heat transfer, which encourages unwanted movement in th...

You'd need to box the part in the way you would if using glue or double-sided tape. Don't encourage readers to do something stupid. Unless left hand cutters are used, the lifting power of a cut will often be enough to pull the part away from the chuck, which no amount of blocking will prevent. As I...

Correct, they won't spontaneously combust, but if the potassium nitrate is introduced well, what it will do is allow the remains of the tree, roots and all, to burn away. That's the idea behind its use. Too bad your stumps aren't alder. After we logged, I had the property scarified. Several smallish...

Boilers are made of elastic materials, so they stretch. Assuming all air is removed from the water contained within, the pressure is the result of the minor stretch of the entire boiler, as water does not compress. It will continue to stretch as more water is injected, assuming one has the ability t...

I won't eat "organic" because the term "organic" doesn't actually mean anything except that the food is more expensive. I agree. Simply a "buzz word" that encourages folks who have little reasoning power to spend money on things that make little, if any, difference. Sort of reminds me of folks who ...

I don't trust any local heat treating shop here to do it properly (my experience with them on other jobs) You didn't mention the problem(s) you've experienced with the heat treating shops, but one thing needs to be mentioned, and that is that heating ANY material, regardless of its nature, tends to...
